to find midpoint, find the mean.

add the numbers together and divide by the amount of numbers there is:

10 + 20 = 30

30/2 = 15

15 is your answer

hope this helps

Distance between 10 and 20 is 10. Half of 10 is 5. Add the 5 to previous 10. 10 + 5 = 15

A parent is buying two types of chocolate truffles for the children. The oldest child likes white chocolate (W), the younger two

valkas [14]

Answer:

Each dark chocolate tuffle was $6.

Step-by-step explanation:

This question can be solved by a system of equations.

Four white chocolate truffles (W) cost the same as three dark chocolate truffles (D).

So $4W = 3D$

The parent bought 3 white chocolate truffles(W) and 6 dark chocolate truffles (D), and spent $49.50.

$3W + 6D = 49.50$

$4W = 3D$

$D = \frac{4W}{3}$

$3W + 6D = 49.50$

$3W + 8W = 49.50$

$11W = 49.5$

$W = 4.5$

$D = \frac{4W}{3} = \frac{4*4.5}{3} = 6$

Each dark chocolate tuffle was $6.

If cos θ - sin θ = √2 sin θ, then prove that cos θ + sin θ = √2 cos θ.

belka [17]

Step-by-step explanation:

cos θ - sin θ = √2 sin θ

cos θ + sin θ = √2 sin θ + 2sin θ

cos θ + sin θ = √2(sin θ + √2sin θ)

cos θ + sin θ = √2 cos θ. (Proven)

The diameter of each wheel of a bicycle is 27 in. If you are traveling at a speed of 40 miles per hour on this bicycle, through

grandymaker [24]

Circumference = πd, where d = diameter

we know the wheel has a diameter of 27 inches, so the total circumference is 27π, and that's the arc length of one revolution.

there are 5280 feet in 1 mile and 12 inches in 1 foot.

so in 40 miles there are 40(5280)(12) inches.

and we also know that there are 60 minutes in 1 hour.

$\cfrac{40~miles}{hour}\implies \cfrac{~~ \frac{40(5280)(12)~in}{27\pi ~\frac{in}{rev}}~~}{60~minutes}~~\approx ~~\cfrac{29878.688~rev}{60~minutes}~~ \approx ~~497.978~\frac{rev}{minute}$
